Polyurethane product with gas fading inhibitor and method of inhibiting the gas fading of polyurethane product

Abstract

A gas fading inhibitor for polyurethanes, such inhibitor having as its effective component a compound of the formula (I) wherein R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen, methyl and ethyl, and n and m are each an integer from 1 to 3.

What is claimed is: 
     
       1. A method of inhibiting the gas fading of polyurethane products which comprises incorporating therein a compound of the formula (I): ##SPC3## wherein R 1 , R 2 , R 3  and R 4  are independently selected from the group consisting of hydrogen, methyl and ethyl, and n and m are each an integer from 1 to 3. 
     
     
       2. Polyurethane product having improved resistance to gas fading consisting essentially of polyurethane and a compound, as the gas fading inhibitor, of the formula, ##SPC4## wherein R 1 , R 2 , R 3 , and R 4  are independently selected from the group consisting of hydrogen, methyl and ethyl, and n and m are each an integer from 1 to 3, in the amount of from about 0.1 to about 10% by weight of the polyurethane.   
     
     
       3. Polyurethane product of claim 2 wherein said compound is N,N'-dibenzylxylylenediamine. 
     
     
       4. Polyurethane product of claim 2 wherein said compound is 1,4-bis(benzylaminomethyl)-2, 5-dimethylbenzene. 
     
     
       5. Polyurethane product of claim 2 wherein said compound is 1,4-bis(paramethylbenzylaminoethyl) benzene. 
     
     
       6. Polyurethane product of claim 2 wherein the polyurethane product is a textile product. 
     
     
       7. Polyurethane product of claim 2 wherein the polyurethane product is a film. 
     
     
       8. Polyurethane product of claim 2 wherein the polyurethane product is a synthetic leather. 
     
     
       9. Polyurethane product of claim 2 wherein the polyurethane product is a coating material. 
     
     
       10. Polyurethane product of claim 2 wherein the polyurethane product is a foamed shaped article.
